Error - AssignmentCannotEditSummaryTask when using QueueUpdateProject

  I am attepting to put together a web application to update selected project tasks on a Project Server 2007 installation. The code I am using is (for the most part) taken directly from the code example in the SDK under the QueueUpdateProject method. I am simply attempting to update the TASK_NAME field on one Task record on an existing project and nothing else. The problem is that upon calling QueueUpdateProject - I am getting error 135 - AssignmentCannotEditSummaryTask for what looks to be several Assignment records. The task I am updating is NOT a summary task. To further complicate things - this error happens even if I comment out the code that makes the change to the project DataSet (not updating the project DataSet at all). Here are the steps I am taking and the results I receive:

  SCENARIO 1:

  • read the project details using ReadProject - SUCCESSFUL
  • check out the project using CheckOutProject - SUCCESSFUL
  • update the TASK_NAME field - SUCCESSFUL
  • call QueueUpdateProject - ERROR HAPPENS HERE

  SCENARIO 2:

  • read the project details using ReadProject - SUCCESSFUL
  • check out the project using CheckOutProject - SUCCESSFUL
  • call QueueUpdateProject (no changes to the project DataSet) - ERROR HAPPENS HERE

  SCENARIO 3: (this Scenario works fine)

  • read the project details using ReadProject - SUCCESSFUL
  • check out the project using CheckOutProject - SUCCESSFUL
  • check in the project using CheckInProject - SUCCESSFUL

  And here is the actual code I am using:

      protected void Button1_Click(object sender, EventArgs e)
      {

          q.Url = baseUrl + QUEUEWEBSERVICE;
          q.Credentials = CredentialCache.DefaultCredentials;

          Button Button1 = (Button)sender;
          GridViewRow grdRow = (GridViewRow)Button1.Parent.Parent;
          Label5.Text = grdRow.Cells[2].Text;  //TASK_NAME field

          int taskId = Convert.ToInt32(grdRow.Cells[8].Text);  //TASK_ID field

          int idx = grdRow.DataItemIndex;
         
          //Get the Project ID from the GridView DataKeys collection
          Label6.Text = GridView2.DataKeys[idx].Value.ToString();
          Guid projectId = new Guid(GridView2.DataKeys[idx].Value.ToString());

          Guid sessionId = Guid.NewGuid();
          Guid jobId = Guid.NewGuid();

          //Read the Project Details
          WebSvcProject.ProjectDataSet projectDs = project.ReadProject(projectId, WebSvcProject.DataStoreEnum.PublishedStore);

          //Check Out the Project
          project.CheckOutProject(projectId, sessionId, SESSION_DESC);

          //Update the Task field on the local DataSet
          Label7.Text = "DS VALUE : " + projectDs.Task[taskId].TASK_NAME.ToString();
          projectDs.Task[taskId].TASK_NAME += " Changed";

          //Save the changes
          project.QueueUpdateProject(jobId, sessionId, projectDs, false);
          WaitForQueue(q, jobId);

          // Check in the project
          jobId = Guid.NewGuid();
          project.QueueCheckInProject(jobId, projectId, false, sessionId, SESSION_DESC);
          WaitForQueue(q, jobId);

      }

  I am VERY new to Project Server development so any assistance would be greatly appreciated.
